Having new particularly described my invention, I hereby declare thatwhat I claim as new and desire to be protected in by Letters Patent, is:

1. Means for controlling the temperature of oil for combustion, saidmeans comprising the combination with a steam ipe delivering steam to anoil heater, an a pipe delivering oil from the heater to the burner, of avalve in the steam pipe controlling the passage of steam therethrough7achamber through which the oilto the burner passes, a container exposedto the oil in the chamber one side of which container is flexible, saidchamber charged with a Huid having a high ratio of expansion under heat,means for connecting the flexible side of the conta incr to the valve ofthe steam pipe whereby outward movement of the fiexible side of thecontainer will operate to close the valve, said connecting meanscomprising a stem on said valve, an extensionstem engaging Athe exibleside of said container, an adj estable turn-buckle connection betweensaid stems, a s ring for maintaining the engagement of aid extensionstem with said flexible side of said container, means for ndjusting thetension of saidspring, said tension` adjusting means comprising a screwadapted to press against said spring, said screw being bored to permitpassage of and having a passage for said extension stem, and means forsupporting said valve and said container to maintain alinement of saidstems.

2. A device of the class described, comprising the combination with a@cam pipe delivering steam to an oil heater and a pipe delivering oilfrom the heater to the burner, of a valve in the steam pipe controllingthe passage of steam therethrough to the heater, an open ended chamberthrough which the oil pipe to the burner delivers from the heater, acontainer having asubstantially rigid side which closes the open end of-the chamber, and a flexible side externally exposed to the air, saidcontainer charged with a Huid having a high yratio of expansion, a stemthe end of which rests on the flexible side of the container,- said stemendwise movable iii a screw threaded into a support secured to thecontainer, a spring between the end of this screw and a washer securedon the end of the stem, .means y:for staying the valve of the steam pipeto the container, and means for adjustably connecting the end of thestem which rests on the container to the stem of the steam pipe valvethat the valve may be opened when the fiexible side of the container isat the inner limit of its movement and will close as it expands outwardfrom that position.

In testimony whereof I aixmy's'ignature.

LESLIE A. IVANY.
